Learn the snowboard shifty: dose the twist, untwist early, land straight – with the DSLV tweak example, landing data and a World Cup study on landing stability.
The honest answer up front: A shifty is a trick in which you twist the board against your upper body in the air, so the legs turn while the shoulders stay, and straighten it again before landing. The most important part is the untwisting: if the board is not straight in the riding direction at landing, you have a problem.
Data support that. In a video analysis of 704 park jumps, an incorrect board position at landing and landings on the flat or knuckle predicted falls, and spinning jumps had a higher fall risk than straight jumps [3]. I found no study on the shifty itself. In its exam the DSLV names as a possible component of a straight air a tweak in which the board is twisted by about 90 degrees against the flight direction [1]. That is related, but not identical to the shifty, and the terms are used inconsistently.
Honestly: the shifty is an intermediate trick with a critical component. Expect several park days until you get the landing straight every time (experience value).
Why learn it anyway? Because it is the basis for many variations: it trains moving upper and lower body independently of each other, and you need that later for tweaks, grabs with a twist and spins (practical experience). The price is that you must not practise the trick half-heartedly. Either you untwist cleanly, or you leave the twist out.
The DSLV describes the jump as inrun, transition, take-off, compact flight phase and cushioned landing [2]. Without a stable straight air there is no shifty.
Milestone: 8 out of 10 straight airs land full base and straight.
On flat ground you make small hops and turn only the legs, about 20 to 30 degrees, while shoulders and eyes stay straight. Then you turn them back in the hop (practice).
Milestone: 8 out of 10 hops with a clean untwist and a straight landing.
Jump the kicker, twist the board only slightly and untwist early. At kickers the DSLV assesses whether the component is clearly performed and the landing is on full base [1].
Milestone: 6 out of 10 jumps with a straight landing.
Untwist the board earlier than you think. The timing of the untwist decides the landing (practice). In a study of World Cup slopestyle jumps, angular velocity, rotational axis and number of rotations influenced the snowboarders’ landing stability, with added interaction effects for switch landings [4].
Milestone: 6 out of 10 with a straight board position already before touching down.
Increase the twist step by step, never suddenly, and only when the landing was straight ten times in a row. The FIS snow park code says: skills must be stable before you move on [8].
Milestone: 5 out of 10 jumps with a bigger twist and a straight landing.
The shifty is a jump with a twist, so it carries risk. In a terrain park, jumps and the half-pipe were at 2.56 injuries per 1,000 runs, rails at 0.43; compared with rails, kickers had almost twice the odds of injury (OR 1.99) [5]. Wrist guards clearly reduced the risk of a wrist injury (RR 0.23; one prevented injury per 50 riders wearing guards). However, non-experimental data suggest they may increase finger and elbow-shoulder injuries [6]. Helmets reduced head injuries (OR 0.65) without a higher neck risk [7]. Never practise when you are tired, and never on a kicker whose landing you cannot see [1]. This guide explains and motivates; it does not replace supervised training.
Turn the shifty into a jump with two conditions: twist the legs and untwist them. The first condition is the trick, the second is the landing. Give yourself a signal in flight, for example a look at the landing that triggers the untwist (practical experience). And practise the jump also without a twist, so the landing does not follow the trick but the trick follows the landing.
You twist the board against the upper body in the air and untwist before landing. I found no study on the shifty itself; the technique is federation methodology and practice.
As an example of a tweak, the DSLV names about 90 degrees against the flight direction [1]. Start with less and increase step by step (practical experience).
In 704 park jumps, spinning jumps were linked with a higher fall risk than straight jumps [3]. An incorrect board position at landing predicted falls [3].
No. You need a safe straight air and full-base landings [1][2].
They clearly reduced wrist injuries, with signs of more finger and elbow-shoulder injuries [6]. Talk to an instructor about the fit.
